My server is live and serving customers. I can't afford to take the box down for a whole day while I upgrade ports. Is there any intelligent way to do this? For example, could I do everything on a second disk while running the live system on the first disk? For example using a chroot so it thinks it's For example, might this work? 1) upgrade system in the canonical way: # make buildworld # make buildkernel # make installkernel # reboot # mergemaster -p # make installworld # mergemaster # reboot 2) make sure misc/compat6x is installed 3) on a second disk or in a directory somewhere like /new a) nullfs mount read-only all the things one needs inside a chroot to work except /usr/local b) create a writable /usr/local, /usr/X11R6, /compat/linux and /var/db in the chroot 4) then for each package installed, install it within the chroot 5) when all that's done, drop into single-user mode and move /usr/local, /usr/X11R6, /compat/linux, and /var/db/pkg to the real system (saving the old ones) 6) reboot Warning, I have never tried this. -Mike On Wed, Mar 19, 2008 at 11:47 AM, Oliver Fromme <olli@lurza.secnetix.de> wr= ote: > Hello Marko, > > I'm very sorry that you have trouble updating your FreeBSD > installation, but there are very good technical reasons to > update your packages, as others have already explained in > detail (i.e. library conflicts). > > When I updated my home workstation from FreeBSD 6 to 7, > I used the opportunity to clean up my installed packages, > which was long overdue anyway. > > First I saved the output from "pkg_info" in a file.
